Summary for the World

El Niño Advisory: El Niño conditions are present. Positive equatorial sea surface temperature (SST) anomalies continue across the western and central Pacific, while near-to-below average SSTs are evident in the eastern Pacific. There is an approximately 50-60% chance that El Niño conditions will continue through Southern Hemisphere winter 2015.

April Wind

Most landmasses will experience average wind conditions for the month other than Western Europe and parts of the Mediterranean Basin with above average wind conditions. Winds will be greater than average in the North Pacific Ocean and through the South Pacific Islands.

April Solar Radiation

Much of the northern hemisphere should expect slightly above normal solar radiation levels for the month. Southern Australia and New Zealand and much of Africa and South America could have slightly below normal solar radiation.

April Temperature Extreme Forecast Index

Northeast Asia and Northeast North America are expected to be cooler and much of the rest of the world near normal accept in the Pacific Ocean where the eastern Pacific will be warmer and central and western Pacific cooler. Coastal China will be warmer than usual.

April Precipitation Extreme Forecast Index

Large parts of Central Mexico and the US Southwest and Southern USA could have extreme precipitation although most areas are just slightly wetter. Central China and Western Africa could have extreme precipitation events. Papua New Guinea, Java and Sumatra and the Southern Malay Peninsula could be unusually dry along with Central Africa.

May Wind

Most landmasses will experience average wind conditions for the month. Northern Australia could be slightly below normal and parts of Africa and southern South America.

May Solar Radiation

May Temperature Extreme Forecast Index

Northeast Asia is expected to be cooler and much of the rest of the world near normal accept in the Pacific Ocean where the eastern Pacific will be warmer and central and western Pacific cooler. Eastern Australia and western areas of New Zealand are expected to be cooler than normal. Coastal China and island SE Asia is expected to be warmer than normal.

June Wind

Most landmasses will experience average wind conditions for the month. Northern Australia and Indonesia could be slightly below normal and parts of Africa and Brazil and southern South America.

June Solar Radiation

Much of the northern hemisphere should expect slightly above solar radiation levels for the month. Southern Australia and New Zealand and much of South America could have slightly to moderately below normal solar radiation along with most of Africa.

June Temperature Extreme Forecast Index

Much of the world’s landmasses are expected to be in the usual low range accept in the Pacific Ocean where the eastern, northern and far western portion of the Pacific will be warmer and the central Pacific cooler. Eastern Australia and New Zealand are expected to be cooler than normal. Coastal China and SE Asia are expected to be warmer than normal along with northern Europe.

June Precipitation Extreme Forecast Index

The US West and south-central South America and Southwest China could have extreme precipitation although most areas are just slightly wetter. Papua New Guinea, and portions of mainland Southeast Asia could be unusually dry along with the Amazon Basin.
